early press release ( beta tester)  ( Russia)

Positive Grid has announced the Spark home multimedia guitar combo.

Spark translates to the great and mighty, like Spark, and this novelty already prophesies the fame of the Yamaha THR killer , because at a much lower price, Positive Grid has ten cool features. As Comrade Ulyanov-Lenin said: "Flames are ignited from a suit" and the Yamaha dictatorship will be overthrown, like Kerensky's interim government.

The design of the Spark amplifier looks very stylish and solid, like any other Positive Grid product. The controls are similar to THR,  there is a tuner, and the effects of modulation, delay and reverb are controlled by separate knobs. The power of the amplifier is 40W. As for the functionality ...

Positive Grid Spark allows you to download images of amplifiers and lotions from the Tone Cloud; today, this library contains more than 10,000  patches .
Tone Cloud gets presets created in Positive Grid Bias Amp Bias Pedal applications , including using Tone Matching cloning .

The amplifier can be controlled by voice commands. Of course, it is not the combo himself who receives the commands, but the smartphone or tablet that controls the amp through the air.

The separate Spark mobile application also lays out any song from iTunes, Spotify or Youtube to chords, displaying them on the screen of a smartphone or tablet. The program dealt with the Blood Group instantly, but on Doo Ter Tam it took half a minute. The application even finds lyrics, and also offers songs with a similar chord sequence. In addition, the application has a game reminiscent of Guitar Hero or even rather Rocksmith and access to huge libraries of video tutorials.

The Smart Jam application, which should appear in the AppStore and Google Play in the near future, and while it is being moderated, will allow you to create a virtual Rome section, like the one implemented in the Digitech Trio pedal , which adapts to your harmony and style.

In addition, Positive Grid Spark can be used as a USB audio interface for recording to a computer. The combo box comes with the free PreSonus Studio One Prime licensed program.



This looks like a really cool new system.
Does anyone have any experience of this yet or any "hands-on" review?


QuoteDear Spark Power Supporter,

We've heard your questions and concerns related to shipping and would like to provide clear and honest communications so you know what to expect. This message is an update related to your Spark order.

We are a few weeks delayed from our original estimated ship dates that are posted on our website (www.positivegrid.com/spark). Why the delay? The response to Spark has gone way beyond what we anticipated for pre-orders. Your overwhelming interest and support of Spark created a unique situation where we had to make major updates to our original production plan. Those changes created a production delay of a few short weeks. We sincerely apologize for the delay and we appreciate your patience. We are confident you will agree that Spark is worth the slight delay after you receive your Spark order.

Our team has been hard at work through the holiday season to ensure Spark units are shipped as quickly as possible. The original shipping estimate for your Spark order was January 2020. We anticipate your Spark order will ship by the end of February.

If you have any questions, please don't hesitate to let us know by writing to us at support@positivegrid.com.

Thanks again for your continued support and excitement about Spark. We can't wait for you to get your hands on your Spark!

Just got this email as a "Group #3 Power Supporter" ( Ordered Nov. 30, 2019 )

Dear Spark Power Supporter,

We're writing to share some updates about your Spark amp and app. As you may know, Spark has been a runaway success, with now over 20,000 pre-orders and a slew of positive feedback from the media, YouTubers and more. In fact, we just unveiled Spark at the NAMM Show in January where it was awarded the "Best Guitar Amp at NAMM" from MusicRadar.

We know you've been waiting for your Spark, and we're sure what you really want to know is, "When will I get mine?" Here's what's happening. The popularity of Spark has exceeded our expectations and the large quantity of orders has resulted in a shortage of an essential component. The good news is we've been able to re-source this component, and our production is back on track. However, this shortage has created a delay past our original estimate for January shipping.

We will be shipping Early Bird and Super Early Bird orders the first week of February. Your order, and those of other Power Supporter purchasers, will follow in the order in which they were received. We anticipate now that you will receive your order by the end of February.

In the meantime, we'll continue to share more news and updates on Spark, and we're excited to get your Spark to you soon. You can follow production updates on our site here.

So, in theory, either today or tomorrow someone should actually receive this thing. I ordered at the beginning of november and the anticipation is killing me. I can't wait to hear some reports from people who aren't paid to like it.


Also, I have a plethora of devices I can use with this. Anyone have any insight as to which is best? I have an Ipad air, a bunch of android tablets, various windows machines (probably not supported at all), and a Samsung note 9 and J7.

I would anticipate a buggy first release at this point in the product lifecycle. It would be great to pick the least buggy environment to start off with.


Review the minimum requirements

Android  - the wireless remote control Spark app runs fine on my LG V20 (Android 9) and Galaxy Tab S3 ( Android 8 ) 

I recall it needs IOS 11 or above  for iPad

the Spark App does not run on Windows

There is one here in UK

in USA , Some Early Bird Spark Orders in USA  claim they got a Fedex tracking number last Friday , but diving into details with Fedex shows only a label was created, and they use Fedex Home  - which never delivers on Monday - so I figure Wednesday is when we will hear of anyone receiving a Spark in USA  at the earliest   


Great, that it will work with either android or IOS for me. I guess I;ll try both and see which has the better interface and reliability.


its arrived for some in USA

So I've played it, really quietly - baby sleeping next room.

sounds pretty good - a bit of fizz but may just be the volume. Cleans good.

Auto track generation didn't work - server error.

So far pretty pleased and quality feels good actually. Knobs smooth turning and solid, switch good and cabinet nice and heavy/solid feeling.Bluetooth connected easily - two step for audio player though.

Good thumbs up, tomorrow I'll turn it up and compare properly.

I've had Spark for 5 days and I'm happier with Spark than with the THR10C - tried them side-by-side and preferred spark. The THR seems scooped to me where the Spark is a bit mid-rangy, I'd like to see an EQ added post-amp or at the end of the signal chain to trim the mids. I like editing with the app, very intuitive and getting some great clean to edge of breakup sounds.

From what I can tell you can't move effects around, and the manual seems to say you can swipe to the side to see what other effects can be loaded into a slot but this isn't working for me. Maybe still some bugs?

Sounds better for bass than the THR10C, but I turned the reverb off in the app and was still getting a little reverb on bass.

Yes, in the effects chain at the top, tap and hold on the effect, then slide up or down to turn it on or off. Tap it twice to open the effects drop down window, scroll to desired effect, then tap desired effect in menu to select. Swipe L/R on effects chain(top) or effect/amp in bottom window, to see all effects and amp in chain.

1st real PG Spark Amp User  review

I received my Spark yesterday (early day 1 order, probably within 30 min of the preorders going live, my order number was 317). I thought I would provide some initial reactions as an educated consumer.

I would not consider this a review of sound quality, and I am not going to demonstrate me playing (you are all welcome). I am not a very good guitarist, and I am not good at dialing in tones, so it would not be a fair review.

What I will do is provide my initial impressions as well as comparative thoughts against the Yamaha THR10ii, which I know many people would compare to the Spark. I owned the original THR10 in the past, and bought the THR10ii while awaiting the Spark delivery with the thought of eventually keeping 1 of them.

Disclaimer: It is brand new, and I certainly don't know all of the ins-and-outs, so I am sure people will find some inaccuracies!

On the positive side:
It is beautiful. Seriously a nice piece of equipment. It is built really well and if you simply looked and touched it you would not be surprised if you were told it was $500+. All of the knobs/switches are top notch and feel very substantial. Really, both the Spark and THR are well built, but overall on the form/quality the Spark is an easy A+ (maybe the THR is an A).
It comes with a USB cable but not an Aux cable (the original THR10 had both, the new THR10ii had neither) as as well as the power brick. I am in the US, so only received the US-type plug as expected.
The app is beautiful looking and super-easy to navigate. It is head-and-shoulders better than the THR app visually, and the Spark has much more configurability than the Yamaha. Changing presets is easier, the number of models/effects is greater, and Spark has built-in jamming tools that don't exist with the Yamaha. The 1 thing Yamaha has that Spark does not is the capability to change cabs (at least to my early knowledge).
Did I mention it is beautiful? (While I do like the appearance of the THR, I think the Spark looks even nicer.)
It sounds very good, full and rich. I don't want to say great, because as mentioned I am not good at dialing in tones, and my playing is even worse! But the presets are significantly better sounding "out of the box" than Yamaha's presets. Also, the output level of each preset is much more consistent than Yamaha's levels (which has been a complaint on the Yamaha thread). Changing presents in the Spark does not cause sudden volume spikes, at least in the ones I've used so far. With the Yamaha, some are soft, others are very loud. Of course, you can edit, but this is just early impression stuff.
It actually pushes air. I had it sitting very close to me for a while yesterday and noticed it pumping air onto my hand as I played.
It is bigger/heavier than the THR, and sounds like a larger and more powerful unit. It is definitely louder, and cleaner when turned up. I've not yet really cranked it up, but you won't be disappointed with volume.
The interaction between the amp and controller (I use an iPhone X) is solid. Switching presets is quick. There is a very slight pause, but it does change presets faster than the THR.

Now, some of the shortcomings:
I am finding that I have to connect the app and the Spark every time I power on. I've not yet determined if this is by design, a bug, or even mandatory in the way Apple apps work. I've not used Spark with an Android device yet. To be fair, the THR has similar connectivity requirements. This could also very well be user error. Plus, in experimenting, I've been in-and-out of apps, connecting back-and-forth between Spark and THR, etc.
I have had a few app disconnections and have also had to power cycle the Spark a couple of times. It seemed to have frozen up, but it could have been user error again.
Having only iPhone/Android apps is a pretty substantial downside in my opinion. The THR offers the phone/tablet apps as well as Mac/PC apps. I generally use the Mac app and find it a much better experience. My wife has an iPad and I've used the iPad app with the THR, but have yet to try the Spark via iPad, I am sure it will be better than the phone app (easier own the eyes, easier to adjust).
I can't stand the tiny headphone volume knob. Yes, small detail, but it is really tiny and when you have cables plugged in, not the easiest to use.
While on the topic of size, I hate the small 1/8" headphone jack. The new THR also has an 1/8" jack, and I very very very very much preferred the 1/4" jack on the original THR.
I only used the tuner 2x, but it seemed to be laggy and not overly responsive. Could have been user error, but getting in and out of the tuner caused me to have to reboot the amp on 1 occasion.
Finally, here's what might be my biggest problem with the Spark because I enjoy experimenting with 3rd party amp sims such as Scuffham S-Gear and Helix Native. I have yet to figure out how, or if, I can use Spark as an interface. Don't get me wrong, I am able to connect it to my Mac and get sounds and I am able to record using Garageband. However, it does not seem to function as a plug-and-play interface like the THR does, and the sounds I do get are very very noisy. I will say that this is very likely my fault in not knowing what to do, but the THR has definitely been a better experience relative to being an interface. When I plug in the THR I see a 2in/2out device in the Mac Audio App. When doing the same with Spark I see 2 separate devices, one being 1in and the other being 2out.

I am sure there is more, both positive and negative, but this should keep all of you busy for a while!

People will pick apart different amps, and likely compare Spark to the THR, Katana, Katana Air, Vox Adio, and others. At $300, this is a seriously strong competitor. You really can't go wrong. If you are an early-bird and paid less, all the better!

Oh, did I mention it is beautiful?
